Application filed. August 12, 1509. Serial No. 512,534.

To all :whom it may concern: I

Be it known thatI, CHARLES E. Goonv SPEED, of Chicago, in'the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Oar-Trucks;

and I do hereby declare the following to be a full, clear,:and exactdescription of the invention, suc as will enable others skilled in theart to hich it appertains to make .and use the same.

This invention relates to improvements in car trucks and moreparticularly to a spring plank construction therefor,-the object of theinvention being to so construct a spring plank from a plate of metalthat it shall possess adequate rigidity; be prevented from accidentaldisplacement and so that it will serve the double purpose of a springplank and also tying means for the side frames of the truck.

Vith this object in View the invention consists in certain novelfeatures of con-' struction and combinations of parts as hereclaims.

In the accompanying drawings, Figure 1.

is a side elevation of a car truck showing the application of myimprovements thereto. Fig. 2 is a view partly in plan and partly inhorizontal section of the samel Fig.1?) is a view in perspective of thespring plank,

and Fig. 4 is an edge view of-the same.

1,-1, represent the side'frames of a truck,

-' each. having a bolster opening "2 provided viiithparallel side-wallsor columns 3.

The side-frames of the truckare tied together'by means of my improvedspring plank 4; This spring plank comprises a sheet of metal having headportions 5 at its respective ends and between these head portions, theside edges of the sheet of metal' com osing the plank are slightlycurved inwar ly and bent to form strengthening ribs 6 which are disposedsubstantially at right angles to the face of the plank. The headportions 5 of the spring plank are provided in opposite edges withrecesses 7 which, when said head portions are placed in the bolsteropenings of the side frames of the umns of said bolster openings,-and,'on account of said connection of the spring plank with saidside-walls or columns, the spring plank will serve to efiectually tiethe side I frames, together.

In Fig. 1 of the drawing a bolster 8 is shown entering the bosteropening of the side-frames 1 and springs 9 disposed between the bolsterand the head portions of the spring plank.

Having fully described my invention what I claim as new and desire tosecure" by Letters Patent, is-

I. A spring plank for car trucks com prising a Hat platehaving-depending integral ribs at its side edges between its ends andprovided at the opposite sides of its ends with notches adapted toreceive the truck columns. 1

2. A spring plank for a car truck, com-- prising a metal plate havinghead portions v at its-Lendsprovided in diametrically opposite edgesw1th notches, having its side edges between said head portions curvedinwardly and provided with strengthening ribs.

3. The combination with the side frames of a'car truck, said side frameshaving bolster openings with vertical side walls or columns, of a springplank fiat on top having notches in diametrically opposite edges of itsend portions, said notches receiving the side walls or columns of thebolster openings in the side frames of 'the truck, and strengtheningribs at the respective edges ofsaid spring plank between the notched endportions thereof.

In testimony whereof, I have signed this specificationin the presence oftwo subscribing witnesses.
